computer keyboard Audio Speaker

One way to quickly and easily make an flat audio speaker is to re-appropriate already printed electronics. This is a speaker which uses the innards of a computer keyboard. A small grid-like layer of silver ink has been applied to a thin plastic surface, which is used to read keystrokes. But if the connections in the conductive grid are broken using the principles of the sparse design, a speaker can be created. This close-up of a computer keyboard grid shows the break points used to create a spiral structure.
